SPECFICATION forming' part of Letters Patent No. 629,959, dated August l, 1899. Application filed February 1l, 1899. Serial No. 705,358. (llo model.)

improve the construction of latches for wagon end-gates, sliding doors, and swinging gates and to provide a simple, inexpensive, and etlicient device capable of securely lookin g such parts and adapted to be quickly Operated to open the same.

A further Object of the invention is to provide a device which cannot be operated by stock and which when used on an end-gate will obviate the necessity'of employing a transverse rod for connecting the sides of a wagon-body and which may be readily operated in a narrow shed or similar place where there is not su dicient roo'rn to remove such a transverse rod.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustratedv in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a portion of a Wagon-bod y provided with an end-gate fastener constructed in accordance with this invention. Fig. 2 is a vertical sectional view of one side thereof, the section being taken longitudinally of the bolt. Fig. 3 is a horizontal sectional view. Fig. 4 is an elevation, partly in section, showing the latch applied to a sliding door. Fig. 5 is an elevation showing the latch applied to a Swingin g gate. Figs. 6 and 7 are detail views of the sections Of the casing. Fig. 8 is a transverse sectional view of the casing. Fig. 9 is a detail view of the keeper.

Like numerals of reference designate co rresponding parts in all the iigures of the drawings.

1 designates a casing substantiallytriangnlar in cross-section and composed of sections 2 and 3, the section 3 consisting of a back orbottom plate and provided at its ends with anges 4, which cooperate with flanges or portions 5 of the section 2 to form sectional ends, and these sectional ends are provided jto be reciprocated and partially rotated to engage its outer end'with and disengage it from a keeper 11. passes through a perforation l2 of the shaft, and by connecting the ends of the spring with the casing and the shaft or bolt the engaging end of the latter is held out of alinement with the slot of the keeper 1l. The end 13 of the spring is iixed to the bolt, and the other end 8 is adapted to slide in the groove of the casing as the bolt is reciprocated. The sections of the casing are connected by fastening devices 14, passing through perforations of lian ges of the section 2 and through registering perforations Aof the back plateor sect-ion 3 and securing the casing to the part to which it is to be connected.

The outer end of the bolt is provided with a tapering substantially triangular lug 15, adapted to extend through a correspondinglyshaped opening 16 of the keeper 11 and to be turned transversely thereof after it has been passed through the same, whereby it is securelyinterlocked with the keeper, and the- The .other end of the spring.

lated to cause the tapering lug 15 to register latch is shown applied to an end-gate 2O of a Wagon-body, and the end-gate 20, which is arranged between cleats 2l in the ordinary manner, is provided with a pair of the latches and has cleats 22 arranged on the exterior of the end-gate and provided with perforations to support the bolts and form guides for the same. Plates or keepers 1l are secured to the outer faces of the sides of the wagon-body, and the said sides and the rear cleats 21 are provided with slots or openings corresponding to the openings 16 to enable the lugs at the outer ends of the bolts to disengage the sides of the wagon-body. The lugs at the outer ends of the bolts engage the outer faces of the sides of the wagon-bod y, and the handle at the inner end of the bolts may be readily grasped to disengage the lugs, and by this construction and arrangement the endgates may be quickly removed and replaced and the latches can be operated in narrow sheds and similar places where it would be impossible to withdraw an ordinary transverse rod.

In Fig. 4 of the accompanying drawings a latch is shown applied to a sliding door 23 similar to those employed on an ordinary barn or shed, and the keeper, which is arranged at the front edge of the sliding door, is disposed over a socket or opening formed in the same. The latch is mounted on the adjacent portion of the building and may be secured by a padlock, as before explained.

In Fig. 5 of the accompanying drawings the latch is shown applied to a swinging gate and the plate or keeper is mounted on a latch-post 24 similar to an ordinary keeper.

' The invention has the following advantages: The latch, which is simple and comparatively inexpensive in construction, is strong and durable and easily operated and may be readily applied to sliding doors, swinging gates, end-gates, and analogous structures. The spring, which is short, engages the bolt and slides in the longitudinal groove of the casing, and it is capable of securely holding the lug in engagement with the keeper, and it may be coiled in either direction to provide a right or left hand latch.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacriicing any of the advantages of this invention.

What is claimed is- 1. A device of the class described comprising a casing provided with a longitudinal groove, a reciprocating bolt mounted in the casing and having a limited rotary movement to engage and disengage the keeper, and a coiled spring disposed on the bolt and connected with the same, one end of the spring being extended and arranged in the said groove, whereby it is interlocked with and is adapted to slide longitudinali)7 of the casing, substantially as described.

2. A device of the class described comprising a casing having a longitudinal groove, a reciprocating bolt provided at its engaging end with a lug and having a limited rotary movement, and a spring arranged within the casing for holding the lug in engagement with a keeper, one end of the spring being connected with the bolt, and the other end being arranged in the groove, whereby it is interlocked with and is adapted to slide longitudinally of the casing, substantially as described.

3. A device of the class described comprising a casing, substantially rectangular in cross-section and having one of its apexes forming a longitudinal groove, said casing being composed of two sections provided with sectional bearings, a reciprocating bolt arranged in the said bearings and capable of a limited rotary movement, and a spring connected with the bolt and having one end arranged in said groove, whereby it is interlocked with and is adapted to slide longitudinally of the casing, substantially as described.

4. A device of the class described comprising a casing provided with a longitudinal groove, a bolt mountedin the casing and provided at one end with a lug and having a handle at its other end with an opening, a spring disposed on the bolt and having one end connected therewith and its other end arranged in said groove, whereby it is interlocked with and is adapted to slide longitudinally of the casing, and a staple arranged to extend through the opening of the handle and adapted to received a shackle or padlock, substantially as described.

In testimony that I claim the foregoing as my own 1 have hereto affixed my signature in the presence of two witnesses.

SOLOMON GLA'l-IN.
